Abstract: A fibre optic mode conditioner (14) for obtaining an equilibrium light distribution in a multimode fibre optic link under test (16). Light is supplied to the link through a gap (34) between two successive fibre optic segments (30,32), followed by a high-curvature region created by wrapping the second fibre optic segment around a mandrel (44). The gap functions as a mode filter, stripping off all but the lowest modes, while the curved region acts as a mode scrambler redistributing the light energy into the intermediate modes.

Abstract: An electric double layer capacitor has a pair of polarised electrodes (10) in the form of electrode bodies each comprising a porous sintered body, and a pair of current collectors (20) for collecting electric charges stored in the polarised electrodes, the current collectors being in the form of electrically conductive films. The electrically conductive films have surfaces dissolved by a solvent and joined to the electrode bodies with dissolved portions of the electrically conductive films being present in pores of the electrode bodies. The polarised electrodes and the current collectors are thus held in stable contact with each other, with a reduced contact resistance therebetween. The electric double layer capacitor thus has a low internal resistance.

Abstract: A medical treatment device (20) is disclosed which includes a medical treatment element (36,38) and resilient securing members (32,34) which adjust or deform to conform to the particular dimensions of that part of the patient's anatomy which is to be treated. The resilient securing members (32, 34) move or deform outwardly away from the patient (22) as the device is applied to conform to the size of the patient and ensure that the patient is centered within the treatment device. The medical treatment elements (36,38) are thus accurately positioned with respect to the patient (22). This is particularly important in treatments involving the application of magnetic fields to the patient (22). In addition, the disclosed medical device (20) is relatively comfortable and can be worn by a patient (22) for a relatively long period of time. 
     The invention also extends to the method of applying the medical treatment device (20) to the patient (22).

Abstract: A contactless inductive data transmission system between at least one transmitting and receiving station (1) and one or more battery-less transponders (3) operates with only one RF signal (Fig. 3) which supplies the transponder (3) with energy, at the same time predetermines the system clock and transmits information by pulse-width modulation. The transponder (3) provides for bi-directional data flow also in a full-duplex transmission, the transponder (3) representing digital data by means of a pulse-code modulated signal which load-modulates (modulator 10) the RF signal of the transmitting and receiving station (1) by adding or disconnecting coils or windings of the antenna coil (10) or a connected coil. Whereas the pulse-width modulation (modulator 7) in the transponder is regenerated to form a digital information by means of a demodulator (15) comprising a pause detector and a subsequent counter, the reconversion from the load modulation in the transmitting and receiving station (1) is effected by at least one demodulator (9) with filter. <IMAGE>

Abstract: A method of fabricating a semiconductor device (10) to retard diffusion of a dopant from a center active region (14) into adjacent regions. The center active region is epitaxially formed by selectively increasing and decreasing an introduction of diffusion-suppressing material, preferably germanium, into a semiconductor material, preferably silicon, so that a vertical profile of the content of the diffusion-suppressing material is such that outdiffusion of a dopant is minimized. One embodiment of the tailoring is to increase the concentration of the diffusion-suppressing material at both of the opposed sides of a base region of a bipolar transistor, thereby providing concentration peaks at the interfaces of the base region with collector (12) and emitter (14) regions. The concentration of germanium in a Si 1-x Ge x  layer is such that the value x is within the range 0.08 to 0.35 and optimally within the range 0.15 to 0.31. The dopant, preferably boron, also has a tailored concentration profile to minimize outdiffusion. A thinner, more highly doped active region is thereby achieved.

Abstract: The uncertainty inherent in high-resolution acoustic pulse-echo distance measuring systems which depend on threshold detection is overcome by transmitting a multi-cycle shot of acoustic energy having a sharply peaked amplitude profile, and locating the peak amplitude of a received echo. The peaked amplitude is achieved by timing the duration of energization of a transducer (8) producing the shot so that energization is terminated before the amplitude of oscillation of the transducer has reached a maximum. This produces a shot which has a definite largest cycle, which should in turn produce an echo having a definite largest cycle.

Abstract: A laser beam emitted from the laser emission unit (20) is emitted through an objective lens (12) and focused on an optical medium. A reflected beam from the optical medium is returned through the objective lens and a diffraction grating (11) to a signal detection circuit (34) in the laser emission unit. Hitherto, many operating functions have been provided in the optical head (1). However, the present invention provides the laser emission unit in a lens holder (10) and with a plurality functions in the emission unit itself and so the space in the optical head can be reduced. Moreover, the space for the light path both emitted and received is also decreased. Thus, the size of the optical head is extremely reduced and since the optical head can be assembled by a smaller number of parts, the production costs can be decreased.

Abstract: A generalized analysis-by-synthesis technique is disclosed. Illustratively, a section of an original signal containing a local maximum energy is identified. A plurality of segments of the original signal containing the local maximum energy are selected based on a plurality of time shifts. These segments are termed "trial original signals." Each trial original signal is compared to a synthesized signal from an adaptive codebook and a measure of similarity ( e.g ., a cross-correlation) between these signals is evaluated. A trial original signal for use in coding is determined based on one or more evaluated measures of similarity. A signal reflecting a coded representation of the original signal is generated based on one or more determined trial original signals. The signal reflecting a coded representation of the original signal may be provided by an analysis-by-synthesis coder, such as a CELP coder.

Abstract: An auto-starting lamp system comprises an electrodeless high intensity discharge lamp of the type including an arc tube that contains an ionizable fill, an excitation coil surrounding the arc tube for exciting an arc discharge in the ionizable fill at least during steady state lamp operation, and a starter circuit for facilitating arc discharge of the ionizable fill. The system further comprises a controllable r.f. power source for powering the lamp excitation coil, and an electrical network for matching the impedance of the excitation coil to the impedance of the r.f. power source. The impedance-matching network has the same impedance-matching relation during both lamp start-up and steady state lamp operation. A system controller causes the r.f. power source, during lamp start-up, to ramp up in power to a peak level preferably substantially in excess of a steady state lamp operating power level, and then to decrease from the peak level. Preferably, the system further comprises circuitry for re-powering the starter circuit after a predetermined period of time has elapsed that is sufficiently long as to prevent thermal damage to the lamp resulting from powering the starter circuit. The system preferably further comprises control circuitry for alternately turning on and turning off power to the starter circuit after the lamp ionizable fill recovers an ability to reach full arc discharge after being extinguished.
